PLANNING THE TESTS
Before commencing testing, it is advisable to take a few minutes to plan. First
of all work out whether the equipment is Class I or II. Then the type of
equipment and the environment it is going to be used in. This will help to
determine how often the inspection and testing has to be carried out. The
Equipment Register then needs to be prepared. Once this is completed, one is
ready to commence Inspection and Testing.
Class of construction
All equipment that uses mains electricity are either Class I or Class II. Knowing
the Class of the equipment is important when planning the testing.
If the symbol is present on the rating plate the equipment is Class II. If the
symbol is missing, assume that the equipment is Class I. Mains extension
leads and IEC leads are treated as Class 1 appliances.
Type of equipment
For the purpose of planning, electrical equipment is categorized into 5 types as
shown below. In general, the easier it is to move an appliance, the higher the
chances of damage to it and the more frequently it has to be tested.
Stationary equipment
: Refrigerators and washing machines
are examples.
Information Technology equipment
: This includes computers, VDUs,
data terminals, telephones, printers, fax machines and photocopiers.
Movable (transportable) equipment
: Items that are moved
occasionally, like fans and fires would fit in this category.
Portable appliance
: These are appliances such as vacuum cleaners, toasters
and kettles which can easily be moved whilst connected to the mains.
Handheld appliance
: This is equipment intended to be held in the hand
during normal use like a hair dryer or drill.
